We proudly present our new 2015-10 DBpedia release, which is abailable now via: http://dbpedia.org/sparql. Go an check it out!

This DBpedia release is based on updated Wikipedia dumps dating from October 2015 featuring a significantly expanded base of information as well as richer and cleaner data based on the DBpedia ontology.

So, what did we do?

The DBpedia community added new classes and properties to the DBpedia ontology via the mappings wiki. The DBpedia 2015-10 ontology encompasses

The editors community of the mappings wiki also defined many new mappings from Wikipedia templates to DBpedia classes. For the DBpedia 2015-10 extraction, we used a total of 5553 template mappings (DBpedia 2015-04: 4317 mappings). For the first time the top language, gauged by number of mappings, is Dutch (606 mappings), surpassing the English community (600 mappings).

From now on, we provide extensive dataset metadata by addingDataIDs for all extracted languages to the respective language directories.

In addition, we revamped the dataset table on thedownload-page. It’s created dynamically based on the DataID of all languages. Likewise, the tables on thestatistics- page are now based onfiles providing information about all mapping languages.

From now on, we also include the original Wikipedia dump files(‘pages_articles.xml.bz2’) alongside the extracted datasets.

And what about the numbers?

Altogether the new DBpedia 2015-10 release consists of 8.8 billion (2015-04: 6.9 billion) pieces of information (RDF triples) out of which 1.1 billion (2015-04: 737 million) were extracted from the English edition of Wikipedia, 4.4 billion (2015-04: 3.8 billion) were extracted from other language editions, and 3.2 billion (2015-04: 2.4 billion) came from DBpedia Commons and Wikidata. In general we observed a significant growth in raw infobox and mapping-based statements of close to 10%. Thorough statistics are available via theStatistics page.

And what’s up next?

We will be working to move away from the mappings wiki but we will have at least one more mapping sprint. Moreover, we have somecool ideas for GSOC this year. Additional mentors are more than welcome. 🙂

And who is to blame for the new release?

We want to thank all editors that contributed to the DBpedia ontology mappings via the Mappings Wiki, all the GSoC students and mentors working directly or indirectly on the DBpedia release and the whole DBpedia Internationalization Committee for pushing the DBpedia internationalization forward.
